The compounds of the present invention are drugs having excellent insecticidal and acaricidal effects not only on those of sensitive lineages but also on pests of lineages resistant to organophosphorus pesticides, carbamate pesticides, and pyrethroid pesticides, and on Acarnia of lineages resistant to acaricides.

Additionally, the compounds of the present invention are drugs that show less herbicide injuries, have lower toxicity to fish and warm-blooded animals, and higher safety.

The compounds of the present invention can also be used as an antifoulant to prevent aquatic organisms attaching to objects which contact water such as ship bottoms (or hulls, alternatively) and fishing nets.

Some of the compounds of the present invention exhibit germicidal activities, herbicidal activities, or plant-growth regulating activities. Moreover, some intermediates of the compounds of the present invention, which are represented by the formula (1) or (3), exhibit insecticidal/acaricidal activities.

The agents for pest control of the present invention have the compounds of the present invention, which are represented by the formula (1) or (3), as active ingredients and the agents can be used either singularly or by mixing two or more thereof. The compounds of the present invention can be used as they are without adding any other components. However, when used practically, they are normally further mixed with solid, liquid, or gaseous carriers, or are impregnated in substrates such as porous ceramic plates and nonwoven fabrics, and by adding surfactants and/or other adjuvants where necessary, used as formulations in the form which general agrochemicals may adopt, that is, wettable powder, granule, dusting powder, emulsion, water-soluble powder, suspending agent, granulated wettable powder, floable, aerosol, transpiration agent by heating, fumigant, poison bait, microcapsule, or the like.

As additives and carriers, vegetable powders such as soy flour and wheat flour; fine mineral powder such as diatomaceous earth, apatite, gypsum, talc, bentonite, pyrophyllite, and clay; and organic and inorganic compounds such as sodium benzoate, urea, and sodium sulfate are used when solid formulation is required. When liquid form of formulation is required, petroleum fractions such as kerosene, xylene, and solvent naphtha, and cyclohexane, cyclohexanone, dimethylformamide, dimethyl sulfoxide, alcohol, acetone, methyl isobutyl ketone, mineral oil, vegetable oil, water, or the like are used as a solvent. As gaseous carriers used in propellant, butane (gas), LPG, dimethyl ether, and carbon dioxide gas can be used.

As a substrate of poison bait, bait components such as grain powder, vegetable oil, sugar, and crystalline cellulose; antioxidants such as dibutylhydroxytoluene and nordihydroguaiaretic acid; preservatives such as dehydroacetic acid; agents for preventing accidental ingestion by children or pets such as capsicum powder; and pest-insect attracting scents such as cheese scents and onion scents can be used.

Additionally, in order to achieve homogenous and stable forms in these formulations, it is also possible to add surfactants if necessary. Although surfactants are not particularly limited, examples thereof include, for instance, nonionic surfactants such as alkyl ether where polyoxyethylene is added, higher fatty acid ester where polyoxyethylene is added, sorbitan higher fatty acid ester where polyoxyethylene is added, and tristyryl phenyl ether where polyoxyethylene is added; sulfate ester salt of alkyl phenyl ether where polyoxyethylene is added, alkyl naphthalene sulfonate salt, polycarboxylate salt, lignin sulfonate salt, formaldehyde condensate of alkyl naphthalene sulfonate, and isobutylene-maleic anhydride copolymer.

When the compounds of the present invention are used as agents for pest control in agriculture, the amount of active ingredient in the formulation is 0.01 to 90 weight % and particularly preferably 0.05 to 85 weight % and wettable powder, emulsion, suspending agents, floable agents, water-soluble powder, granulated wettable powder which are diluted to predetermined concentrations with water, and dusting powder and granules as they are, can be applied onto plants or soil.

In addition, when the compounds of the present invention are used as agents for pest control in quarantine purposes, emulsion, wettable powder, floable agents, and the like are applied by diluting to predetermined concentrations with water and oil solution, and aerosol, poison bait, anti-acarid sheet, and the like can be applied as they are.

When the compounds of the present invention are used as agents for pest control in controlling ectoparasites of livestock such as cattle and pigs or of pets such as dogs and cats, formulations using the compounds of the present invention are used in known methods in the field of veterinary medicine. As such methods, examples thereof include a method for administering in forms such as tablets, capsules, immersion liquid, feedstuff mix, suppository, and injection (intramuscular, subcutaneous, intravenous, intraperitoneal, or the like) when systemic control is required and a method for administering by spraying, pouring-on, or spotting-on oily- or aqueous liquid formulations or a method for mounting objects, which are resin formulations shaped into collars, ear tags, or the like, when non-systemic control is required. In this case, the proportion can be normally used where 0.01 to 1000 mg of the compounds of the present invention are applied per 1 kg of host animal.

It should be noted that although the compounds of the present invention are, needless to say, sufficiently effective even when used solely, they can also be used by mixing or combining with one or more of other agents for pest control, germicides, insecticides/acaricides, herbicides, plant growth regulators, synergists, fertilizers, soil conditioners, animal feed, or the like.

Test Example 1 Effectiveness Against Tetranychus urticae

17 adult female Tetranychus urticae, which were resistant to organophosphorus pesticides, were inoculated on the first true leaf of a common bean, which was seeded in a pot with a diameter of 9 cm, where 7 to 10 days had passed after the germination. After the inoculation, the drug solution, which was prepared by following the method of the wettable powder shown in Example 1 of the drugs and by diluting with water to achieve the compound concentration of 125 ppm, was applied. The pot was placed in a temperature-controlled room where the temperature and humidity were set to 25° C. and 65% respectively, and the adulticidal rate was examined 3 days after the application. The test was repeated twice.

As a result, the compounds below showed the insecticidal rate of 100%. 1-1, 1-4 to 1-7, 1-10, 1-13, 1-17, 1-18, 1-21 to 1-29, 1-31 to 1-36, 1-39 to 1-47, 1-50, 1-51, 1-54, 2-3, 3-1, 4-5, 4-7, 4-9, 4-13, 4-16, 4-18 to 4-20, 4-53 to 4-55, 4-58 to 4-61, 4-64, 4-70, 4-71, 5-1 to 5-8, 10-1, 11-1, 13-2, 15-1, 15-17, 16-1 to 16-26, 16-61, 16-65, 16-69, 16-73 to 16-75, 16-78, 16-82 to 16-91, 17-2, 17-3, 17-7 to 17-10, 19-1 to 19-3, 21-1, 21-3, 21-5, 21-6, 21-14 to 21-16
